INTERVAL
1.
Set
up
the
Starting
Patch.
2.
Turn
the
INTERVAL
control
from
UNISON
to
OCTAVE.
(This
moves
the
pitch
of
OSC
2
one
octave
above
OSC
1.)
Gently
moving
the
control,
listen
until
the
beating
effect
disappears.
Fine
tuning
will
ensure
a
perfect
octave
interval.
3.
Now
experiment
with
finding
intervals
between
UNISON
and
OCTAVE.
Setting
the
oscillators
at intervals
enriches
the
tone
quality.
Settings
of
a
perfect
fifth
or
fourth
are
frequently
used
because
of
the
organ-like
tone
colors
created.
Moving
the
Interval
control
left
of
UNISON
will
give
OSC
2
intervals
below
the
pitch
of
OSC
1.

Remember
to
return
the
Interval
control
to
UNISON
when
completing
this
exercise.
Notice
once
more
that
the
"beating
effect"
will
disappear
when
the
two
oscillators
are
exactly
in
tune.
However,
slow
beating
(slight
detuning)
does
produce
a
fatter
sound.

control.
Notice
the
changing
tone
color
while
moving
this
control.
Experiment
with
different
settings.
4.
Return
the
